Problems solved by technology

However, due to the presence of unsaturated double bonds in the ABS structure, the weather resistance of PC-ABS alloy products is poor, which cannot meet the requirements of PC-ABS alloy materials for automotive interiors. Therefore, it is necessary to modify the weather resistance of PC-ABS materials

Embodiment 1-4

[0036] Mix the dried PC resin, ABS, ABS-g-MAH resin, additives and toner according to the composition ratio in Table 1, and then use a twin-screw feeder to continuously and evenly add to the twin-screw extruder (screw diameter 35mm, aspect ratio L-D=36) In the main barrel, the temperature of the main barrel is controlled in sections (from the feeding port to the nozzle outlet) to 180°C, 210°C, 240°C, 250°C, 250°C, 255°C, 245°C, and the twin-screw speed is 300 rpm / minute, the extruded strips are cooled in a water tank and then pelletized to obtain the product. Above-mentioned product is injection molded into standard spline with plastic injection molding machine after drying at 85 ℃ for 4 hours in blast oven, and injection molding temperature is 250 ℃. The injection-molded strips were immediately placed in a glass desiccator at room temperature for at least 24 hours before performance testing. The test results are shown in Table 1.

Abstract

The invention discloses a highly weather-resistant colored polycarbonate-acrylonitrile-butadiene-styrene resin blending material and a preparation method thereof. The blending material is prepared from the following raw materials in parts by weight: 40-60 parts of polycarbonate resin, 35-55 parts of acrylonitrile-butadiene-styrene grafted copolymer, 0-5 parts of acrylonitrile-butadiene-styrene grafted maleic anhydride compatilizer, 0.1-2 parts of light absorber, 0.2-0.7 part of antioxidant and 0.1-1 part of coloring agent. By adoption of the highly weather-resistant colored polycarbonate (PC)-acrylonitrile-butadiene-styrene resin (ABS) blending material, when the PC / ABS material is prepared into different colors, the weather resistance data of the material is greatly improved by adjusting the toner proportion due to an experiment under the condition that a weather-resistant aid combination is optimized, and the blending material can be used for automobile interior and exterior parts, household appliances and the like.

Description

technical field [0001] The invention relates to a highly weather-resistant colored polycarbonate-acrylonitrile-butadiene-styrene resin blend material, which is directly colored into the final required product color, has excellent weather resistance, and can use different colors for different colors. The powder ratio is used to improve the overall weather resistance of the material. Background technique [0002] PC-ABS alloy material has the excellent properties of both PC and ABS. On the one hand, its heat resistance and impact resistance are better than ABS materials. On the other hand, its melt viscosity is lower than that of PC, and its processing performance is better than that of PC materials. PC-ABS materials are widely used in various fields, such as various interior and exterior parts of automobiles, home appliances, office products, etc. However, due to the presence of unsaturated double bonds in the ABS structure, the weather resistance of PC-ABS alloy products is...
